Are you sure you did correct instruction how to insert LG Quantum unlock code in your phone? As my knowledge when we do unlocking phone we insert the original sim card not the unaccepted sim card. Try doing that procedure again but this time use orignal sim card when you insert lg unlock code in your phone. Good luck!

A request for a PUK code ("Personal Unlocking Key") will appear on your phone if your SIM card PIN code is entered 3 consecutive times incorrectly.

Your SIM card will then become "PUKed" or Blocked. This is a security measure to protect your service.

You need to call the Customer Service department of your cell phone provider and they will give you the PUK code which will unblock your SIM card.

hello,the only person to unlock the phone for you freely is your service provider,all you need to do is just to call them and give them your mobile number and imei number.there are no free codes available for it now.

wish you good luck,

take care.

No one can give you free lg tu500 unlock code unless you describe your carrier network and your phone imei number. To generate lg unlock code, carrier information and imei number is needed since one single phone has one unlock code.

That means that your sim card is either not capable with this phone or that the sim card is broken.

One question: when did you get the phone?

i bought my phone throught e-bay too i got optus sim card ask me about secuirty code (sos) i just put 4 zero ( 0000) the phone accepted and un locked try that

Try the SIM in another phone. SIM cards go bad.
If it doesnt work in the other phone it will have to be replaced. I
THis can also be caused if you set up a PIN code and it was entered in wrong too many times and you did not use the right PUK code to unlock it. THis will permanently damage a SIM card.
f it does work in another phone then your phone is no longer able to read SIM cards. Check with the manufacturer for warranty info.

I suggest reducing the size of the SD card to a 512mb and you should have no problem. There have been problems with the 1GB for these phones and I mhave 2 of these phones and they both have 512mb with no problem any larger and they keep giving error messages
